Anyone have any advice for finding an HVAC contractor in the Boston MA area who has a Carrier USB-L cable and knows how to use it?
I'm a board member for a condo building that has 63 units with Carrier WSHPs and ZS Pros as "thermostats" in each unit. They're all configured for central management/connectivity but not actually wired to our BMS. We'd like to be able to unlock/adjust the ranges of the ZS Pros for owners, but we've been having a heck of a time finding a contractor who actually understands what we're asking for.
As far as I can tell we just need to find someone who has a USB-L cable (and the appropriate software) who can do this. But ... I can't find anyone to do it. Am I asking the wrong question? Any advice? Should we just buy one off eBay? I'm worried about the software/licensing aspects, more than anything, but I also don't want to be getting stolen goods, etc.
